tain new and useful Improvements in Movin'g-Picture Machines; and I dohereby dethroughout the and on which the roller 5 These sprlngs clarethe following to be a full, clear, and exact description of theinvention, such as' will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to newand useful improvements in moving picturemachines.

An object of the invention resides'in the provision of a device by meansof which the film maybe kept taut during the feeding of the same fromone roll to the other so that the film at the shutter will be preventedfrom buckling.

With this and other objects in view,- such as will appear as thedescription progresses,

my invention comprises the combination and arrangement of parts as setforth in and falling within the scope of the appended claims.

Referring to the drawing:

Figure 1 is a front elevation of my device, showing the same attached toa pro ecting machine. Fig. 2 is a side elevation thereof. Fig. 3- is avertical sectional view taken through thefilm. Fig. 4 is a plan view.

Referring to the drawing wherein like parts are indicated by likecharacters several views: in the embodiment of my invention shown in thedrawingI- have provided a pair of rollers 1 and .2 which are disposedhorizontally and in vertical alinement. The uppermost roller is' adaptedto be mounted upon the frame of the" projecting machine by means ofbrackets 3 so that it will be freely rotatable. The lowermost roller 2is suspended, by means of springs from the roller 1, which springsnormally contact with the roller'l when there is no film therebetween. Apair of similar rollers 5 and 6 are provided; The roller 6 is rotatablymounted on brackets 7 which are adapted to be secured tothe framev ofthe machine. The roller 5 is mounted on springs 8 which extend from theroller 6 is rotatable. 8 normally maintain the roller 5 in engagementwith the roller (5 when there is no film disposed bet yeen them.Extending between the rollers 2 and 5, at the ends maintain the roller 2in tionedrollers,

thereof, are springs 9 which normally tend" to force the rollers 2 and 5toward the re spective adjacent rollers 1 and 6.;

In using this device the best results are obtained by the use of a film10 which winds ,from a spool 11 onto a second sp'ool mounted within afilm magazine '12. This film has a binding strip 13 on each edgethereof, which strip may be made of rubber, leather or any othersultable material. These strips protect the film and prevent it fromtearing.

In operation thefilm 10 is fed from the spool 11, between the rollers 1and. 2, is then carried downwardly and between the rollers 5 and 6 ontothesecond spool. movement of the film from the spool 11 to Patented Feb.15, rare.

During the e i the spool 12 the rollers l and 2 and the roll- I 'on theedges thereof by the springs i and 8,

respectively. During this movement. of the film the portion disposedbetween the rollers 2 and 5 will be kept taut by the action of thesprings 9, which tend to separate the rollers 2 and 5, and, because ofthe presence of the binding strip 13 on the film, will prevent thebuckling of the film between these rollers. Thus this portion of thefilm, which is the portion which is exposed to the light. is kept tautand consequently the projecting of the figures will be constant. 7

From the foregoing description it .will be seen that I have provided adevice for maintaining the portion of a film, on a moving picturemachine,through which the light is projected, taut so that the bucklingof the film will be prevented. \Vhil'e l have illustrated and describeda particular embodiment of my invention, I

venience and'l do not'wish to be limited to that particular embodimentas it is obvious that numerous changes may be made within the details ofconstruction thereof without in any way departing from the spirit of theinvention or exceeding the scope of the appended claims.
